ZYD Series Double-Stage Vacuum Transformer Oil Filtration can quickly and effectively remove moisture, gas (Hydrogen, acetylene, methane, etc.) and impurities from the insulation oil, to improve the oil dielectric performance. The filtered oil can effectively ensure the power equipment run safely and normally. ZYD Double-stage vacuum oil purifier is widely used in power supply, power generation, power transmission and transformation, power equipment manufacturing, power engineering, electrical equipment maintenance, power testing, electrical research and other industries. It is especially suitable for the filtration of high-grade transformer oil and ultra-high transformer oil, and can be applied to online oil filtering operations at the power substation (like 110KV / 220KV / 500KV). Meanwhile, ZYD oil purifier has the functions of vacuum drying, vacuum oil injection, and hot oil circulation. It can also be used as a separate vacuum pumping unit to evacuate transformers and power equipment.
◆ The vacuum system uses the roots pump as the main pump and the rotary vane vacuum pump as the primary pump. Fast start-up, large pumping speed, stable performance, and high ultimate vacuum of less than 5Pa.
◆ Double horizontal vacuum separators, combined with Duplex-Stereo film evaporation technology
◆ Strong ability to remove impurities: ultra-large area cylindrical precision filter element, with high filtration accuracy, easy installation and replacement.
◆ Low-load heating: Adopt advanced internal and external double-tube heat radiation indirect heating technology.
◆ Automatic control to realize unattended, safe and stable working.
◆ Safety interlock protection for oil pump, vacuum pump, heater,keep safely working
◆ Low noise, easy operation, long maintenance interval, low energy consumption, low operating cost
◆ It can be used together with the insulation oil regeneration device, which has the effect of decoloring, deacidification, deoxidation and removing free carbon and other harmful substances from the oil.
